ROCKING-CHAIR.

SPECIFICATION forming part of Letters Patent No. 328,000, dated October 13, 1885.

Application filed July 16, 1885. Serial No. 171,771.

To all whom it may concern.-

Be it known that I, FRED. H. BROWN, a

I citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented a new and useful Improvement in Rocking-Chairs, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to an improvement in rocking-chairs; and it consistsin adetachable rocker and a clamp for securing the rocker to the legs of an ordinary chair for the purpose of converting the latter into a rocking-chair, as will be set forth more fully hereinafter.

The object of my invention is to provide a rocker and a clamping device for securing the rocker to the legs of an ordinary ehair,whereby a rocking chair may be obtained at a very small cost.

In the accompanying drawings, Figure 1 is a side elevation of an ordinary chair, with rockers attached thereto by means of my improved securingclamps, and thereby converted into a rocking-chair. Fig. 2 is a detailed perspective View of a rocker and the securingclamps. Fig. 3 is a detailed sectional view through the chair-leg, rocker, and clamp.

A represents an ordinary chair having the legs a.

Rockers B are made of suitable form and size, and are adapted to be attached to the lower ends of the chair-legs by clamps 0. These clamps consist of the sections 0 c,wh'ieh are concavo-convex in cross-section, and are secured together by a screw, 0, that passes through aligned openings in the sections. The opening in the section 0 is interiorly threaded to receive the threaded shank of the set-screw,

(No model.)

and the opening in the section 0 is smooth, thereby causing the screw to bind the sections together. At the lower ends of the sections are inwardly-extending spurs 0 These sec tions are placed on opposite sides of the rocker, and the lower end of the chair-leg is inserted between the upper ends of the sections. The set-screw is then turned, which clamps the sections tightly against opposite sides of the rocker and the lower end of the chair-leg and embeds the spurs c in the sides of the rocker, thereby firmly securing the chair-leg and the rocker together. The function of the spurs is to prevent the clamps from slipping or working loose on the rocker.

By means of this invention an ordinary chair may be readily convertedinto a rockingchair in a very short time and at aslight cost, thus bringing a rocking-chair within the reach of any one, however poor.

Having thus described my invention, I claim The combination, in a chair, of the rockers and the clamps for securing the rockers to the legs of the chair, said clamps consisting of the semi-cylindrical sections 0 c, inwardly-projecting spurs 0 adapted to enter the sides of the rocker, and the set-screw o for clamping the sections together on the sides of the rocker and the lower end of the chair-leg,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
